Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 4 generators on 24 points:

(1,2,4,5)(3,6,7,8)(9,10)(11,14)(12,13)(15,16);(2,5)(6,8)(17,18,20,23)(19,21,24,22);(1,3,4,7)(2,6,5,8)(10,13)(14,16)(18,21)(19,24)(22,23);(3,7)(6,8)(9,11,12,15)(10,14,13,16)
